What is Thermal Paper?

Paper that is impregnated with a chemical that changes color when exposed to heat.  It is used in thermal printers and particularly in lightweight devices such as adding machines, POS cash registers, credit card terminals and facsimile machines.



What are the storage and shelf life recommendations?

Store thermal paper in a dark place at relative humidity between 45% and 65% and with temperatures below 25o C will assure satisfactory performance for at least 3 years from the date of manufacture. We recommend that thermal papers not be exposed for long periods to direct sunlight, ultraviolet light sources, vinyls, plastics, shrink wraps, adhesives, wet-toner copies or certain carbon papers.



How long is the image retention?

Once the thermal paper have been imaged on the recommended equipment, it is expected that the image will remain legible for at least 5 years, assuming the documents are properly stored with compatible materials under normal filing conditions, with a relative humidity between 45% and 65%, as well as with temperatures below 25o C.

Thermal paper uses dye and coreactant technology to form an image. The combination is slightly sensitive to ultraviolet (UV) light and may exhibit some image decline with extended exposure to office light or shorter exposure to intense UV light.
